Is there anything I'm missing? Anything I can do to help debug the

Nope. The next line afer what's shown above is after the machine resets. This is a server, so I get full BIOS redirection. I know I'm not missing anything there.

I don't see anything directly wrong, but it's obviously "not as it
should be".

What version of gcc are you using - if you have a bleeding edge
compiler, maybe it clobbered the binaries in some way (we've seen
problems where new compilers optimization features causes Xen to "go
wrong" because the compiler makes assumptions about things that aren't
matching reality). Gcc 4.0 or older should be fine tho'.
